MINE CAR.

Continuation of application Serial No. 14,142, filed. March 9, 1925. This application filed July 15, 1925.

Serial No 43,774.

In the drawings:

The figure is a vertical sectional view showing a car wheel and axle bearing with the improved bearing tightening means in place.

This application is a continuation of application, Serial No. 14,142, filed March 9,

1925, and one object of the invention described herein is to provide a bearing ad justing means which may be operated to tighten the bearing without it being necessary to remove a car wheel from the axle.

Another object of this invention is to provide a bearing adjusting means which will permit of a car wheel being removed from its axle without interfering withthe adjust? ment of the bearing of the axle. Another object is to provide a bearing adjusting means of the type described so constructed that at the limits of its movement ample clearance is provided between the Wheel hub and the journal box and bearing. In mine cars of the type shown the wheels are mounted upon the axles in such a manner that they are disposed outwardly. beyond the journal boxes and with the structures now in use in mine cars it has been found difficult to adjusta so-called Timken hearing to compensate for wear as it is necessary to remove the wheels before the bear-' ings can be adjusted. By having the wheels mounted in accordance with this invention the bearings can be adjusted without removing the wheels thereby saving a great deal of time and trouble. This improved construetion also permits the wheels to be fastened to the axles so that the wheels and' axles turn together and permits the wheels to be removed from the axles without disturbing the bearing adjusting means.

In the illustration only one wheel has been shown together with an end portion of an axle but it will be understood that a similar construction will be provided at each end of the axle. This axle 1 extends transversely of the mine car and projects through a hearing or journal box 2 .which is dis posed-beneath a shoe 3 secured to the under face of the side sill i of a car body. This bearing 01' journal box 2 is of a conventional construction and carries roller bearings 5 which are also of a conventional construction and disposed upon opposite sides of .the annular rib 6 in the journal box. Collars about the spindle-form portion 0 7 and 8 are disposed at the inner and outer ends of the journal box, the collars being provided with packing 9 for retaining a lubricant in the journal box. The inner collar 7 fits updn a tapered portion 10 of the axle 1 whereas the collar 8 is dis seleid t e axle. It will be obvious that when it is desired to adjust the hearings to compensate for wear it is simply necessary to force the collar 8 inwardly towards the collar 7, whereupon the roller bearing assembly will be moved to take up wear or to proper operative relation.-

The wheel 11 is disposed upon the extended outer end portion of the axle and has its hub portion 12 extended outwardly beyond the spokes and rim and this extended outer end portion of the hub is pierced transversely with alined openings 13 so that a transverse wheel-securing bolt 14 may be [passed through the hub and through a transversely disposed opening provided in the axle. This bolt is provided with a securing nut 15 which when tightened will securely hold the bolt in place. It will therefore be seen that when the bolt is put in place and the nut secured the wheel and the axle will turn together. Therefore 'when the car is in use and moving along a track the axle will rotate in roller bearings and will be permitted to turn easily.

It is desirable to permit the bearings to be adjusted when they have become worn and in order to do so there has been provided a sleeve 16' which extends through and beyond the hub of the wheel at each end and fits snugly upon the extended end portion of the axle, with its inner end in contact with the collar 8. The sleeve 16 is of greater length than the hub of the wheel and its end portions extend beyond the ends of the hub when necessary. Openings 17 are provided in the sleeve to receive the bolt 14 and these openingsl? are elongated longitudinally of the sleeve so that the sleeve may be moved longitudinally of the axle. The length of the sleeve 16 is sufficient. however. to provide ample clearance between the wheel hub 12 and the journal box 2 and collar 8 when the sleeve 16 is in its outermost position, that is, upon the application of a new or unworn hearing. A nut 18 is screwed upon the reduced and'threaded outer end portion 19 of the axle and engages with or is formed with a washer which is of such size that it will engage with the outer end of the sleeve 16 but whose diameter is less than the diameter of the bore of the wheel so that the wheel 11 may be removed from the sleeve 16 or replaced thereon without disturbing the nut 18 and washer 20 or the adjustment of the bearing. By adjusting this nut properly pressure will be applied to force the sleeve inwardly through the hub of the wheel and its inner end will force the outer collar 8 inwardly towards the inner collar 7 and cause the desired adjustment of the bearings. After the bearings have been adjusted the desired amount the cotter pin 21 will be put in place and the adjusting nut will be held inthe proper position holding the collar 8 in .adjusted position. \Vhen the bearings have become worn so that they need adjusting it is simply necessary to remove the cotter pin and the nut 18 can be moved to again move the sleeve inwardly and cause further adjustment of the bearings. It will thus be seen that with this construction the bearings can be adjusted without it I being necessary to remove the wheel.
